JOSIAH AUSTIN, OF NEAR EAST LIBERTY, OHIO.

WATER-FEEDER FOR BOILERS.

SPECIFICATION forming part of Letters Patent No. 368,990, dated August 30, 1887.

' Application filed April 20, 1886. Serial No. 199,500. (Model) To all whom it may concern.-

Be it known that I, JOSIAH AUSTIN, a citizen of the United States, and aresident of near East Liberty, in the county of Logan and State 5 of Ohio, have invented a new and useful Improvement in Water-Feeders. for Boilers, of

which the following is a specification. 7

My invention is an improvement on my application No. 168,544, feed-water for steami l boilers.

Figure 1 is an end view. Fig. 2.is a side view showing parts of the cross-heads in section,

with the connections between the chambers,

standard) for supporting my chambers FF,

: E,'pivots in the corner of'my frame; F F, globular chambers, which altcrnatel y receive the water from the tank and feed it to the boiler; G G, flexible pipes that connect the chambers F F with the rotating T-heads H H;

I I, stationary transverse pipes in the T-heads,

through which the water passes to the chainbers and to the boiler; K, hose or pipe leading from the tank to the upper T-head, H; M M, valves to prevent reflux of water and 5 steam; N, air-cylinder having diaphragm 0 playing therein to break the shock as the I chambers rise and fall; P, piston carrying the diaphragm O; Q Q, joints in piston to allow it to play perpendicularlyin the air-cylinder;

S S, diaphragms in the transverse pipes I;

- T T, ports through which the water is admitted; II, pipes conveying steam from the boiler.

into the chambers, where it is condensed, forming a vacuum.

The'operationof my improvement is as folwith the highest chamber, F, and communication opened to it from the tank, when the water rapidly fills it. It is then let go of,

when it descends, establishing a connection H around pipe I.

through port T with the pipe lead-ing to the boiler, and opening connection between the tank and the other chamber, F, which fills with water as the chamber F is emptying into the boiler through pipe I. When a sufficient quantity has entered the chamber F to overbalance the weight in the lower chamber and the friction of the parts and that of the airchamber, the chamber F descends, is connected with port T, and is emptied into the boiler through pipe I, while chamber F ascends again, is connected with port T, and is filled again.

U is a steam-pipe leading from the waterline in the boiler into the upper T-head, and connecting with the chambers FFalternately through ports T'T. Through this pipe and ports T'T the steam is admitted to the chamber being emptied, equalizing the pressure between the chamber and the boiler, heating the water, and condensing the steam, thetcondensing steamlforming a vacuum and assisting the flow of water into the chamber when the influx-port is opened again into it. Any eX- cess of steam is carried into the tank through pipes K. The steam is admitted alternately to the chambers T T, which are opened and closed alternately by the rocking of the pipe When the water rises above the desired water-line, it fills the lower end of the pipe U, preventing steam entering the chambers and stopping the operation until steam is admitted again into the outflowing chamber andpressure equalized.

What I claim as new is--- 1. In a boiler-feeder, the combination, with standard B and pivoted frame 0, of the chambers F F, pipes H H I 1, ports T T, and the diaphragms S, placed obliquely across the pipes and so arranged that the water shall be admitted to and emptied from the chambers at the bottom,while steam is alternately admitted to the chambers through the top, as and for the purpose set forth.

2. The combination, with pipes H H II, portsT T, and diaphragm S, placed obliquely across the pipe, of the flexible tubes G' G and chambers F F, as and for the purpose set forth.
